Specification of Letters Patent. Application filed''anuary 31.1906. Serial No. 298,876.

Patented Jan. 8, 1907 Fo all' whom, it may concern:

Be it known that I, WiLLIAM BAYLEY, a citizen of the United States, residing at Springeld, in the county of Clark and State of Ohio, have invented certain new and usefull Improvements in Corn-Shellers, of which the following is a specification.

n My invention relates to corn-shellers, such as are employed for domestic use, and more particularly to `hand-operated devices as dis` tinguished from power-driven machines.

l The object of the invention is to provide a simple, light, and inexpensive machine for she.ling corn and automatically sepa-.ating the cobs from the shelled corn.

A further object is to provide a construction employing a minimum number of parts so shaped as to be readily cast yand which may be assemb. ed without the necessity of machine-work, thereby greatly Afacilitating the manufacture i A further object is to provide a device which will readily and automatically accommodate itself to varying sizes of ears of corn. With the above primary and other incidental objects in view the invention consists of the means, mechanism, construction, and mode of operation, or-their equva ents, hereinafter described, and set `forth in the claims. l

In the accompanying draw ngs, Figure 1 is a i font elevation of the assembled machine.

Fig. `Z-is a vertical sectional view. Fig. 3 is a plan view of the device, showing its relation to the side of the box or receptacle to which it may belattached Fig. 4 is v'aninterior view of the shell or frame.` Figs-75,6, and 7 arel details ofthe driving connection for the toothed shelling-wheel.

l Like parts' are-indicated by similar characters` of reference throughout the several views. i l l Y Referring by letter to the drawings, a. c represent the respective parts of the main frame. f

Y o' is a hopper formed in the upper part of the frame. y

i Project ng inward from the shell portion a of the main frame is a hub c3 forming the bearing for a shaft a4. The open front side of the-main frame is covered by a dishshaped disk a5 mounted on the shaft a4. The'disk af may be secured directly to the shaft a buty is preferablyformed with clutch-teeth as at c, Fig. 3, to engage similar teeth in the hub porton of a hand e c7,

by which the shaft a4 and connected parts 'are revolved. The hande c7 is secured to I-Iowever, 1t.

the shaft c4 by a` set-sci ew as. is obvious any other su table means might be employed for connecting the hand e c7 and the disk a5 with the shaft a.

The '.nterior of the main fiame parts a a are so shaped as to form in general outline a three-way conduit, ofwhich the' hopper' or intake c forms one arm, the discharge-cionduit a0 for shel.ed corn, located on the under side of the device, forms the second arm, 'and the righthand side in Figs. l, 3, and 4, forms the third arm. Within the shell portion a of the main frame, immediately below thehope per a2, is a series of inclined ribs all, vwhich act upon theear of corn in the nature of internal screw-threads, as will be explained.

Loosely journaled on the hub o3 and spring-pressed in the direction of the shell a by a spring b is a toothed shelling-wheeIb. The toothed wheel b is slightly convex on its inner surface, as shown in Figs. 2 and 5, and is provided with a series of projecting studs or teeth b2, adapted to engage the grains of corn and disengage them from the cob. It is further provided `with a series of elongated teeth b3, which are arranged, preferably, about midway from the center of the said wheel to the periphery .and in staggered rows. These teeth are longer than the shelling-teeth land somewhat pointed, so as to engage between and project through the kernels and engage with the cob, and thus insure the rotation of the ear. in shelling, in a manner hereinafter more fully described. The toothed wheel thus describedfis caused to revolve upon .rotation of the handle a7 by means .of flexible connections with the disk a5, :which consist of a plurality of links b4, hinged at opposite ends to the disk a5 and the toothed wheelA b. Thelinks b4 are hinged to both the disk w" and the toothed .wheel b by a peculiar method, the object of which is to facilitate the manufacture and assembling of the de,- vice. Referring particularly to. Figs. 5, .6, and 7, it will be seen that in general outline the links b4 are L-shaped. At each endof the link, perpendicular to the plane thereof and extending beyond the link in both directions, is a stud or trunnion b5 be. Located at intervals about the periphery of the toothed wheels b are perforated bosses 57. The portion of toothed wheel immediately adjacent to said bosses is preferably cutaway or rethe discharge-conduit alo for cobs, ocated to IOO TIO

lthebosses 127 of the toothed wheel.

cessed, -as at t8, Figs. and 6, in order to facilitate the engagement of the trunnion t vwith the boss t7. The disk a5 is indented, as at b", at points in corresponding relation with The inner end of said indent is perforated for the reception of the upper portion of the trunnion-, as shown in Fig. 5. Immediately below the indent b9 upon the inner surface of the disk a5 are bosses blo, arranged in pairs, having angular recesses in their adjacent sides, whereby they will be adapted to receive and hold the nut b of the bolt 512, extending through the disk a5. After the link b4 has been placed in engagement with the disk a5 by extending the upper portion of the stud b5 through'the perforation in the indent b9 the bolt 512 is inserted, and the nut b prevents the accidental withdrawal of the stud b5 from'its engagement with. the disk. The toothed wheel b is capable of a limited movei ment'independent'of the disk ai, but when so rotated, on account of its linked engagement with thedisk a, it will be moved in the direction of said disk, as shown in dotted lines in Fig. 6, or when an ear of corn of larger size is inserted in the device the toothed wheel will clined ribs au.

lshelled therefrom at the'same time by the be forced back against the tension of the spring b and at the same time will be slightly rotated upon the hub a to the position as shown in Fig. v6. However, this limited movement is only permitted in one direction, movement in 'the opposite direction. being revented by the bearing of the foot 613 of the ever b4 upon the outer surface of the toothed wheel t, as shown in Figs. 2 and 6.

In operation the device as thus far described is secured tothe edge of a box or bin or other suitable receptacle by means of a bolt extending lthrough a lug als, projecting from the shell portion a of the main frame. The handle is turned while the respective fears of corn are fed into the hopper a2, where they are'engaged by the revolving toothed "wheel and caused to revolve therewith, in

which movement they are assisted by the in- The kernels `of corn are toothed projection on said wheel, which 'move at different speeds with. reference to the ear of corn, owing to their relative positions between the center and periphery of The teeth also assist in feeding lower end of the conduit el", and by .further revolution of the wheelv and the engagement of the teeth thereof with said cob it is carried upward again and discharged from the mouth of said conduit.

The shaft 0,4 is extended entirely through the main frame of the device and secured to the end thereof. Opposite the handle a7 is a,

head c, having thereon a plurality of projecting figures c inclined on their inner or adj acent edges to form a conical interior. It has been found in practice that machines of the type described, while separating the greater part or all the well-formed kernelsv of grain from the cob, will leave the small or mal- ,formed kernels adhering to one or both ends effectually disengage said kernels.

From the above description it will be apparent that I have produced a corn-Sheller possessing the features of advantage enumerated as desirable and which obviously is susceptible of modification in its form, proportion, detail construction, and arrangement of the parts without departing from the principle of construction involved or sacrificing any of its advantages. Y
